Script Query

[Hunki]

I have this script which I want to run :

#!/bin/ksh
# Script to monitor the IPC's count

Q1=`/usr/bin/ipcs -q|wc -l`
Q2=`/usr/bin/ipcs -s|wc -l`
Q3=`/usr/bin/ipcs -m|wc -l`

if [ Q1 -gt 140 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com
fi

if [ Q2 -gt 120 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com
fi

if [ Q3 -gt 300 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com
fi

Can someone point out why its not running and how to make it run.

Thanks!

use set -x option after #!/bin/ksh line and execute so that you can see why it is not running.

wrong:
if [ Q1 -gt 140 ]

right (well, at least the syntax is correct):
if [ ${Q1} -gt 140 ]

Hi Hunki,

Aside from what Clay said, you're not specifying the absolute path to the 'wc' binary, as you are for other binaries. Also send a test message to hh@hh.com to rule mail transport problems out.

You need a message body, try this:

#!/bin/ksh
# Script to monitor the IPC's count

Q1=`/usr/bin/ipcs -q > /tmp/q1;wc -l /tmp/q1`
Q2=`/usr/bin/ipcs -s > /tmp/q2;wc -l /tmp/q2`
Q3=`/usr/bin/ipcs -m > /tmp/q1;wc -l /tmp/q3`

if [ Q1 -gt 140 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com < /tmp/q1
fi

if [ Q2 -gt 120 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com < /tmp/q2
fi

if [ Q3 -gt 300 ]
then
/usr/bin/mailx -s "xxx" hh@hh.com < /tmp/q3
fi

Maybe you should use full path for wc .

Hi,

combine the solution of Clay and Ivan and it will work:
- use $Qn to get the value of a variable
- the mailx program reads from stdin
- set the PATH variable for cron scripts
E.g.

PATH=$PATH:/usr/bin
Qq=$(ipcs -q | wc -l | tee /tmp/Qq)
[ "$Qq" -gt 140 ] && mailx -s q_overflow hh@hh.com ...
